Magnetic resonance imaging (MRI) findings of subchondral bone marrow edema (SBME) in osteochondral lesions of the talus (OLT) after arthroscopic microfracture are associated with poor clinical outcomes. However, the relationship between SBME volume change and clinical outcomes has not been analyzed. It was hypothesized that clinical outcomes correlated with SBME volume change and extent of cartilage regeneration in patients with OLT.

64 patients who underwent arthroscopic microfracture for OLT were followed up for more than 2years. SBME volume change was measured by comparing preoperative and 2-year follow-up MRI. Clinical outcomes were assessed using the visual analogue scale (VAS) and the American orthopedic foot and ankle society ankle-hindfoot scale (AOFAS) at the 2-year and final follow-up. To compare clinical outcomes, patients were categorized into two groups decreased SBME (DSBME) group (cases without SBME on either MRI or with a decreased SBME volume between the MRIs) and increased SBME (ISBME) gnot affect clinical outcomes.

SBME volume change correlated with clinical outcomes after arthroscopic microfracture for OLT. Clinical outcomes were worse in patients with new postoperative SBME and increased postoperative SBME volume. In patients with an unsatisfactory clinical course that show decreased SBME via postoperative MRI, an extended follow-up in a conservative manner could be considered.

It is expected that, due to differences in dispersal abilities between plants and soil biota, range-expanding plant species will become associated with a partly new belowground community in their expanded range. Theory on biological invasions predicts that outside their native range, range-expanding plant species may be released from specialist natural enemies, leading to the evolution of enhanced defence against generalist enemies. Here we tested the hypothesis that expanded range populations of the range-expanding plant species Centaurea stoebe accumulate fewer root-feeding nematodes than populations from the original range. Moreover, we examined whether Centaurea stoebe accumulates fewer root-feeding nematodes in expanded range soil than in original range soil. We grew plants from three expanded range and three original range populations of C. stoebe in soil from the original and from the new range. We compared nematode communities of C. stoebe with those of C. jacea, a congeneric species native to both ranges. Our results show that expanded range populations of C. stoebe did not accumulate fewer root-feeding nematodes than populations from the original range, but that C. stoebe, unlike C. jacea, accumulated fewest root-feeding nematodes in expanded range soil. Cabotegravir solubility dmso Moreover, when we examined other nematode feeding groups, we found intra-specific plant population effects on all these groups. We conclude that range-expanding plant populations from the expanded range were not better defended against root-feeding nematodes than populations from the original range, but that C. stoebe might experience partial belowground enemy release.In this study, K. oxytoca KMS004 (ΔadhE Δpta-ackA) was further reengineered by the deletion of frdABCD and pflB genes to divert carbon flux through D-(-)-lactate production. During fermentation of high glucose concentration, the resulted strain named K. oxytoca KIS004 showed poor in growth and glucose consumption due to its insufficient capacity to generate acetyl-CoA for biosynthesis. Evolutionary adaptation was thus employed with the strain to overcome impaired growth and acetate auxotroph. The evolved K. oxytoca KIS004-91T strain exhibited significantly higher glucose-utilizing rate and D-(-)-lactate production as a primary route to regenerate NAD+. D-(-)-lactate at concentration of 133 g/L (1.48 M), with yield and productivity of 0.98 g/g and 2.22 g/L/h, respectively, was obtained by the strain. To the best of our knowledge, this strain provided a relatively high specific productivity of 1.91 g/gCDW/h among those of other previous works. Cassava starch was also used to demonstrate a potential low-cost renewable substrate for D-(-)-lactate production. Production cost of D-(-)-lactate was estimated at $3.72/kg. Therefore, it is possible for the KIS004-91T strain to be an alternative biocatalyst offering a more economically competitive D-(-)-lactate production on an industrial scale. KEY POINTS • KIS004-91T produced optically pure D-(-)-lactate up to 1.48 M in a low salts medium. • It possessed the highest specific D-(-)-lactate productivity than other reported strains. • Cassava starch as a cheap and renewable substrate was used for D-(-)-lactate production. • Costs related to media, fermentation, purification, and waste disposal were reduced.Salmonella spp. can cause animal and human salmonellosis. In this study, we established a simple method to detect all Salmonella species by amplifying a specific region within the flgE gene encoding the flagellar hook protein. Our preliminary sequence analysis among flagella-associated genes of Salmonella revealed that although Salmonella Gallinarum and Salmonella Pullorum are lacking flagella, they did have flagella-associated genes, including flgE. To investigate in detail, a comparative flgE sequence analysis was conducted using different bacterial strains including flagellated and non-flagellated Salmonella as well as non-Salmonella strains. Two unique regions (481-529 bp and 721-775 bp of the reference sequence) within the flgE open reading frame were found to be highly conserved and specific to all Salmonella species. Next, we designed a pair of PCR primers (flgE-UP and flgE-LO) targeting the above two regions, and performed a flgE-tailored PCR using as template DNA prepared from a total of 76 bacterialtional bacterial culture-based detection method. It is worthwhile noticed that identification results using flgE-tailored PCR should be completed within less than 1 day, expanding the result of much faster than the standard method, which took more than 5 days. Overall, the flgE-tailored PCR method can specifically detect flagellated and non-flagellated Salmonella and can serve as a powerful tool for rapid, simple, and sensitive detection of Salmonella species. KEY POINTS • Targeting flgE gene for all Salmonella spp. found. • The established PCR assay is used to specifically detect all Salmonella spp. • The PCR method is applied to detect clinical Salmonella spp. samples within less than 1 day.Progressive multifocal leukoencephalopathy (PML) is a rare opportunistic infection with high mortality rate usually seen in the context of immunosuppression. Although cases have been reported largely in patients with HIV/AIDS, following the use of monoclonal antibodies and occasionally in haematological malignancies, there is no review to date of patients with smouldering or treated myeloma who developed PML. Here, we conducted a literature search of PML cases in patients with multiple myeloma (MM), analyse patient and disease characteristics and describe the possible mechanisms that could lead to the development of PML. The lack of data and case reports until 2010 may indicate that PML in MM is underdiagnosed. Simultaneously, with an expanding field of new therapeutic options, patients with MM live longer, albeit continually immunosuppressed, and at risk of opportunistic infections. Emerging new treatments for PML in the horizon render the need to look out for this complication mandatory, and more case reports are needed to enrich our knowledge in this field.

Scoliosis in patients with neuromuscular disease is a common issue and leads to secondary impairment. It is thus important to help such patients to regain and retain best possible stability to improve their quality of life. One option is the double-shelled brace (DSB). The aim of this study was to provide information on the degree of correction when using a DSB on patients with neuromuscular scoliosis.

We included patients with neuromuscular scoliosis treated with double-shelled braces in this retrospective study. Radiographs of the full spine were taken with and without the DSB, the Cobb angles were measured and compared. The correction was expressed in percent of the lumbar and thoracic Cobb angles. In addition, compounding factors such as age, sex, type of the curves, and movement disorder were included.

We analyzed data from 84 patients with scoliosis with different neuromuscular disorders. The mean age was 12.3years (± 5.9). In the lumbar spine we detected an improvement of 27.5% (SD ± 32.9), in the thoracic spine 25.3% (SD ± 38.0).

Short-term corrections with a double-shelled brace in neuromuscular scoliosis present an average improvement of one fourth of the lumbar and thoracic Cobb angles and, independent of age, sex, movement disorder, shape or type of the curve. Only spasticity has an influence on the lumbar scoliosis outcome.

The easily recognisable features that are known to even the earliest xiphosurans-a crescentic prosoma and often trapezoidal thoracetron (opisthosoma)-have generated debate surrounding their origins and taxonomic significance. This interest resulted in the description of numerous horseshoe crab species during the early to mid-twentieth century, particularly in Russia, that have remained unrevised since their original publications and unconsidered in the light of recent phylogenetic hypotheses. Here, we re-examine the non-belinurid taxa housed within the Chernyshev Central Museum for Geological Exploration in Saint Petersburg. We present the first formal diagnosis of Bellinuroopsis rossicus, erect Shpineviolimulus jakovlevi (Glushenko and Ivanov, 1961) comb. nov., to contain the species formerly described as 'Paleolimulus' jakovlevi and refer Paleolimulus juresanensis to Paleolimulidae incertae sedis. Phylogenetic analysis places S. jakovlevi at the base of Limulina. This position, coupled with a prosomal shield that is notably larger than the thoracetron, and lack of hypertrophied genal spines, suggests that this morphology may represent the ancestral austrolimulid shape. As an extension of this revision, we assessed the general austrolimulid morphological characters and uncovered two possible groups of these bizarre xiphosurids.

Cranioplasty (CP) is considered as a straightforward and technically unchallenging operation; however, complication rates are high reaching up to 56%. Presence of a ventriculoperitoneal shunt (VPS) and timing of CP are reported risk factors for complications. Pressure gradients and scarring at the site of the cranial defect seem to be critical in this context. The authors present their experiences and lessons learned.

A consecutive series of all patients who underwent CP at the authors' institution between 2002 and 2017 were included in this retrospective analysis. Complications were defined as all events that required reoperation. Logistic regression analysis and chi-squared test were conducted to evaluate the complication rates according to suspected risk factors.

A total of 302 patients underwent cranioplasty between 2002 and 2017. The overall complication rate was 17.5%. Complications included epi-/subdural fluid collection (7.3%) including hemorrhage (4.6%) and hygroma (2.6%), bone graft resorption (5.
